The Pistons are adding another undrafted free agent to their roster for training camp, having signed former USC forward Nikola Jovanovic to a contract, according to RealGM’s transactions log. Jovanovic confirmed the agreement himself on Twitter, announcing that “it’s official!”

Jovanovic, who worked out for the Pistons just a few days before the 2016 draft, wasn’t selected in June after forgoing his senior year at USC to become draft-eligible. In his final season with the Trojans, the 22-year-old averaged 12.1 PPG and 7.0 RPG, shooting 52.4% from the field.

The Pistons have 14 players on guaranteed contracts on their books for 2016/17 so far, so the team’s final roster slot could be up for grabs in training camp. Jovanovic will face some stiff competition for that opening though — so far, Detroit has added Lorenzo Brown, Ray McCallum, and Trey Freeman on non-guaranteed deals. The club still has two more open spots on its 20-man offseason roster.

Jovanovic’s deal is believed to be for one year, and will likely be worth the minimum salary ($543K), with little to no guaranteed money.
